    Brother Speedio drill program acting differently/wrong

    I don't see you calling out either a G98 or G99.

    taking .01 off raw stock

    I have to do the same with .187x2x3 pieces and do them 2 at a time end to end without issues. I have the program loop so the spindle never stops, no coolant, and the door stays open. Not excactly kosher but one man shop so no one to catch me and 600 parts in around 90 minutes so fast enough. I...

    coolant gone bad?

    You will probably get better answers if you call the manufacturer, but yes coolant does have a shelf life. I think most manufacturers say 1 year but talking, verbally, to a tech should give you far more information. Good question about calibrating your refractometer. I only use one coolant so...

    "Win the Lottery" Home Garage Machine(s)?

    Okuma M560 or something in that line with plenty of options and a small and large rotary so I have one of the right size for the job. Hey, you said win the lottery so I am not going to dick around with toy mills for a garage shop for prototypes and small runs. I want something with a bit of size...

    Looking for recommendations for flexible "fabric" way covers.

    Just a thought for PVC coated fabrics. They also have a neoprene fabric but it's a lot more $.

    Milling 75A duro polyurethane sheet?

    Try millling with a double cut burr that is used for fiberglass laminate, so grinding.

    OT: Anyone ever / Can you machine ceramic tile

    That would cause way too much chipping in the glaze to be useable.

    OT: Anyone ever / Can you machine ceramic tile

    I machined ceramic, quartz, and stone on the same VMC for 15 years and didn't see any wear on the machine from it so it can be done if you take the time to protect the machine properly.

    OT: Anyone ever / Can you machine ceramic tile

    I used to make switchplates from it so yes it is quite machinable with the right tools, but you don't want those chips in your machine. If it were me I would use an angle grinder for that job. Is the tile soft or hard body? It might be better to set the cover on a bead of color correct caulk...

    fusion 360 or something better?

    I only got a graphics card about 6 years ago, and what I have is pretty lame, not even 4k. I didn't notice any difference over the onboard graphics. Until 6 years ago I had 4 megs of DDR2 ram. How long since you wiped Fusion off your computer and did a clean install? Same for the operating...

    fusion 360 or something better?

    It is interesting how different our experiences are. One of my workflows is to model the parts in separate files, insert derive them into an assembly file, insert derive that into another file to create the CAM paths from. The CAM file may also have a fixture inserted into it, that has clamps...

    fusion 360 or something better?

    I have been using Fusion since before you could pay for it and was on the CAM beta team before it was released. How much I liked it was closely related to how familiar I was with it. Many of the issues I had with it were from not knowing how it was supposed to be used and in the end I couldn't...

    Tool Life, Hydraulics, and more

    I did a big volume steel job and we would swap the rougher when the chips started sticking to the cut surface, which would cause issues for the finisher. The finisher always was in great shape when it replaced the rougher. Saves on swapping tools in the holders too.
